AUtlb-TIRE scorn.

To all whom it may concern:

Be it known that we, WILLIAM L, DYSAR'! and CHARLES HENRY LANIUS, citizens of the United States, both residing at Harlowton, in the county of Meagher and State of Montana, have inventedcertain new. and useful.

Improvements in Auto-Tire Scopes; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as-will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in automobile attachments, and-consists more particularly in an improved device for showing the condition of-inflation of the tires to the occupant of the drivers seat in the vehicle. V r j It is an object of the present invention to provide a device for theabove described purpose which will be simple 'in construction styles of automobiles.

and capable 'of application the various It is well recognizedat the present time that tires should be kept at a given degree of inflation, dependent upon the weight of the car, in order to secure the best results in referred to.

automobile operation; and it is a further ob-. j'ect-of the present invention to have the con- .dition of the four tires show on the dash or instrument board of the vehicle so as to be constantly in view of the driver, and the same thus forms a reminder that-the tires showing a condition of partial deflation should be pumped to the given degree abovedrawings forminga In the accompanying part of this application, -and in which-simif lar reference symbols indicate corresponding parts in the several views: 1 I 5 Figure 1 shows an automobilein-dotted lines with a tire scope thereon constructed in accordance with the present invention,

Fig. 2 is an enlarged viewim roved device in s1de elevation.

ig. 3 is a front view of the improved device with the reflector shield tion; and p I Fig. 4 is a s lar view, with parts shown in section and with the shield open. 3

Referring more particularly to the drawin closed posie I ings, in Fig. 1 there is indicated at 1 an automobile or other vehicle using pneumatic tires 2, and 3 indicates the dash or instru-' ment'board ofthe vehicle.

The improved device-consists of a tube showing the that passcsthrough the flopr ofthe automobile and carries reflectors or mirrors at the lower end for reflecting the bases of the various tires up through thetube, which lat,

'ter is provided at its upper end with a recording reflector; ada' ted to receive the carrying 'a pair ,of rear mirrors 7 and 8 shown'in Fig. 4, and a pair of front mirrors 9, one of whlch is shown in Figs..1 and 2.

These various mirrors or reflectors are held by the brackets 5 and 6'below the lower end of the tube 4, and in such position and at the proper angles to reflect the. bases of the four tires 2 of the vehicle. For-instance, the mirror or reflector .7 shown in Fig. 4 and indicated in Figs. 1 and 2, is so placed and arranged thatit will reflect the base of the right rear tire; while'theother mirror 8 is so placed and arranged that it will reflect the base of the leftrear tire of the vehicle. .In likemanner the two front mirrors or reso set and arrangedthat the reflected ra s from the" tire bases will ascend vertically up throughythe tube 4, and this tube 4' ispref- .erably provided with a partitionlO to 'dlvide thesame accordance with the size of'the mirrors orreflecto'rsin orderthat therays may not interfere with one another or beside by side, resp'ectively, above theseveral mirrors.

Brackets 11 onthe upper end of the tube r 4 carry a 'recording'mirror or reflector 12 ar come confused" in the tube.-; or, if desired, 7' twotubes 4 maybe employed and placed ranged on the dash or; instrument board 13, a

above the tube 4 as to intercept the vertica ly ascending rays at substantially a right angle into the vehicle, where the same may be ob- .served by the occu ants. As indicated in ig. 3, the recording reflector 12 may be divided by a horizontal 'line 13' so as to separate the two images of the front tire bases from the. images of and-so placed and arranged 'at such an an 1e the rear tire bases, and if found desirable or necessary a vertical partition line might also be laid off on the recording reflector 12 in order to separate the images of theri ht and left tires.

' ferring to Fig. 4, I the image of the left rear tire would be reflected from the mirror 8 to the upper left hand portion of mitted from the two fr ont'lilirrors 9, would be seen, respectively, at the right and left lower portions of the recording reflector 12 below the line 13, so that each tire has its ima e reflected on the recording reflector 12 inc ear view of the operator, who. may thus be informed as to whattires, if any, have become deflated. v

The shield 14, of a cup-like construction, is adapted to normally fit over the mirrors 7, 8 and 9, as shown in Figs. 1, 2 and 3, so as to protect these various mirrors from dust,

which would otherwise accumulate on same and prevent the proper transmission of the images to the recording reflector 12.

A flange 15 on the shield 14 is adapted to strike a shoulder 16 on the lower end of the tube 4 in order to form a stop or abutment for the shield when the same is in the raised or closed position.-

I The shield 14 is carried by arms 17 ,being merged at their upper ends Where they carry a pin 18 loosely fitting in a slot 19 in one end of the bell crank lever 20, fulcrumed as indicated at 21 on the tube 4 or steering post of the vehicle.

After the condition of the tires has been examined in-the recording reflector 12, the driver depresses the handle of the bell crank lever .20 and restores the shield 14 to the closed position shown in Figs. 1, 2 and 3.

- It is'obvious that those skilled in the art may vary the details of construction and arrangements of parts without departing from the spirit of ourinvention, and therefore we do not wish to be limited to suchfeatures I except as may We-claim: 1 In combination with an automobile hav-' ing. pneumatic tires, of a device for informing occupants in the automobile of the be required by the claim.
